"Be it known that IjWrLLrAM'E. CUERIE, a citizen of the United States ofAmerica, re

Asidingat Detr.oit,in the county of Wayne and State of Michigan, haveinvented certain new .andA useful Improvements in Dumping- .companyingjdrawings.

lThe invention relates to dumping-wagons,

and moreparticularly to that type in which the tilting :of the'bottornsection of the Wagon to discharge lthe load'lifts the sides of thewagon-box and after the load isY discharged the weight of saidbox-.operates to return the tiltedvbottom to normal position.

"The invention consists in certain novel features of construction, ashereinafter set forth. i

In the drawingsfFigure 1 is a central longitudinal section, and Fig. 2is a top plan view.

Y Heretofore dumping-wagons have been constructed in which the box ofthe wagon` body is hinged at its rear end to the frame, the bottom boardof said body being pivotally secured to the frame, so as to be capableof tilting and in so doing raising the forward end of the box. Thelength of the wagonbody is limited to that which will permit the bottomsection to tilt to the required angle for discharging its load, andlgreater length cannot be obtained without correspondingly raising theheight of the frame above the ground. Thus to secure the necessary.capacity for the wagonbox the sides thereof must be considerablyincreased in height over ordinary constructions. With the presentinvention I have increased the length of the wagon-box by extending theframe rearward beyond the rear axle, limiting the length of the tiltingbottom section which raises the box so as to clear said axle andproviding an auxiliary tilting bottom section for the portion of the boxin rear of the axle. I have further provided connections by which themovement of the rear section of the bottom is automatically effectedbythe tilting of the forward section. I

A is a forward truck, B the rear axle, and

,C a frame connecting the same and which projects rearwardly beyond therear axle.

D is the wagon-box, comprising sides and ends, which is connected to theframe C at its rear end by a hinged connection E.

F is a bottom section which extends beneath the forward portion of thebody, terminating just in front ofthe rear axle, said section being`pivotally secured to the frame at G at a point forward of itscenter,sothat the load supported on'the section will be out of balance. Theforward end of thesection F, has a bearing .onthe lower edge oftheforward portion ofthe wagon-box, and thus when the section istiltedsaidbox willbe raised.

In rear of the axleB is a bottom section H, which is also pivoted, butpreferably tothe box D instead of the frame, as at a. v"The location ofthispivot is such in relation'to the rear axle that when 4the body D islowered into its normal position a portion of the section H willrestuponthe axle B.. andwillbe supported therebyin contact with thebox.As soon,l however, asthefbox D is raisedthe shifting of position of thepivot @relative to the axle willpermit the section H to assume theinclined position necessary to discharge its load. Upon the dropping ofthe wagonbox the section H will be again tilted upward by contactingwith the axle B during the lowering of the pivot a.

In order to prevent the material constituting the load in the wagon fromlodging in the axle and going beneath the portion of the section Hresting on said axle, I preferably provide a guard over the adjacentedges of the sections F and H. This guard I, as shown, also constitutesa division of the wagon-box, being inclined forward from its base to thetop, so as to produce a hoppershaped receptacle above the bottom sectionH. A second guard J is preferably secured to the rear axle B andarranged to roje'ct upward between the separated walls and c of theguard or division I. This second guard is for the purpose of preventingany of the load in the forward portion of the wagonbox from dischargingon the axle after the box is raised and the guard I carried therebyabove the axle.

To support the load, locking-latches are provided for the tiltingsections F and H, which are shown in the form of dogs K and L, connected'for simultaneous o eration by the rod M and actuated by suita leconnections. (Not shown.) Thus to discharge the load it is merelynecessary to disengage the IOO dogs K and L, which will permit theweight IIO As soon as the load is discharged the weight of the box willreturn the sections, which may be locked by the dogs K and L, restoringthe wagon in a condition for. receiving another load.

What I claim as my invention is 1. In a dumping-wagon, the combinationwith forward and rear axles, of a bottom formed of two tilting sectionsand a wagonbox resting on said sections, one of said sections extendingbeneath the forward portion "of the box and terminating adjacent to therear axle and the other extending over the rear axle to the rear end ofsaid box.

2. In a dumping-wagon, the combination with forward and rear axles, of aframe supported thereon and extending rearward be yond the rear axle, avwagon-box hinged to said frame at its rear end, a tiltingt bottomsection pivotally secured to said frame and extending over the forwardend of the body to the rear axle, said section being adapted in tiltingto raise the forward end of the body, and a second section pivotallyconnected to said box and extending over the rear axle to the rear endof the box.

'3. In a dumpingewagon, the combination with a box, of tilting bottomsections for said box and a division for said box forming a guardcoveringV the adjacent ends of said tilting sections.

4. .In a dumping-wagon, the combination with a frame andvertically-movable boxwalls thereon, of a bottom for said box formed ofa plurality of tilting sections, one of said sections being pivoted tosaidA frame and adapted to raise the box in tilting and another sectionbeing connected to the box and tilted by the rising thereof.

5. In a dumping-wagon, vthe combination 4o with a frameandVertically-`movable`box walls thereon, a bottom for'said box formed oftwo tilting sections, one of said sections extending from the forwardend of the box to
